Common Problems with the Jeep Cherokee Turbo Diesel and a Replacement Fuel System
Although the Jeep Cherokee turbo diesel is one of the most emblematic engines for a four by four vehicle and has a huge fan base world wide, it is not without its share of problems. The first challenge when buying one is whether to go with the diesel engine or the gas one. The advantage with the diesel is that it is marginally more economic than the gas engine. On the downside mechanical repair and maintenance may not be as readily available.
Replacing the Heads on a Turbo Diesel if Power Begins to Fade
The reason why most people choose the turbo diesel is that the engine has long been compared to the engine on a farmer’s tractor. It is powerful and can propel the Jeep Cherokee over any type of terrain and tow heavy loads. For these applications the diesel engine in general is a much better choice. However it has individual alloy cylinder heads that tend to crack. If you have a diesel that keeps losing power, it may very well be that you will have to get a mechanic to change the cylinder heads.
Switching to Liquefied Petroleum Gas an Alternate Fuel System
Another problem with the Jeep Cherokee turbo diesel is that it consumes a lot of fuel so some people have chosen to make the switch to LPG, or liquefied petroleum gas, which is less expensive. However, that change does come with its own host of problems, including cost. The first problem that a driver will notice will be a drop in power while driving on LPG. The second problem is that the rubber gas lines can give out and you will need to change them if you start smelling gas in the car. You will also have to keep an eye on the switch that makes the transition from LPG back to diesel, as they also tend to fail after a while.
A Common Problem is the Starter Motor
One common problem for a Jeep Cherokees turbo diesel is the fact that the starter engine can fail and it is hidden deep in bowels of the engine. If you notice that the car runs smoothly once you get it going but it is very difficult to start it in the morning and a battery change does not solve the problem, then you may have to change the starter motor. It is not an impossible task for a home mechanic, but you will have to set aside an entire day for the change. This is because you will have to take the entire turbo system out to get at the starter motor. A professional mechanic might be able to do the change in one afternoon but, if this is your first time taking the engine apart, you will need more time.
Maintenance Rules on the Turbo Injector System
Another problem that most Jeep Cherokee drivers have reported is eventually or later you will start feeling the engine losing power for no apparent reason and the heads show no sign of cracking. It will generally happen as you reach sixty miles per hour because at that speed the turbo should kick in and help the engine run better. If there is any problem with the turbo system, the jeep will not exceed sixty miles per hour and you will have to check the usual suspects that can take out a turbo. The first thing to do is to change the air and fuel filters as they can easily be clogged up after about 20,000 miles. If that does not work you should also check the entire turbo injector system for loose clamps or holes that take away from air pressure. If that is not the problem, you will probably have to change one of the injectors, usually the number one injector, but that is really something that you should let a professional mechanic handle.
The Jeep Cherokee turbo diesel has a faithful following almost everywhere in the world. It is a relatively easy engine to work on, unless you have to change the starter motor. The engine will run fine as long as you change all the filters and oil regularly. If you are one of those people, who has an LPG conversion on your Jeep Cherokee turbo diesel, you already know how much cheaper it can be to drive relating to fuel cost. If what you really want is a powerful, reliable Jeep Cherokee and do not care that much about the fuel costs, you should consider the gasoline engine version as an alternative to the diesel.
